Fig. '7 is a view similar to Fig. 4, showing a I 5 Claims.

This invention relates to containers for paste such as tooth paste or shaving paste or similar material or substance, and more particularly to those that comprise a container body of fixed shape and size, with a flexible sack or bag therein filled with the said paste, the container having .a discharge outlet for the paste, and having an opening at one side thereof through which pressure can be exerted against the said sack or bag to expel the paste through said outlet. In a general way, therefore, this invention is in the nature of an improvement on the construction shown and described and claimed broadly in prior application Serial'No. 189,372, filed February 8, 1938, and in prior application Serial No. 234,437, filed October 11, 1938.

Generally stated, therefore, the object of the invention constituting the improvement is to provide a novel construction and arrangement whereby an expeller in the container is unnecessary, as a part of the container, but in which one might be used if desired, one side of the container being left open to provide an opening through which pressure of the finger can be exerted directly against the sack or bag, or against some portion thereof, to expel the paste through the discharge outlet of the container, the said sack or bag being fastened in place at the upper end thereof, adjacent the said outlet, so that even without an expeller or the like, the sack or bag filled with paste cannot drop out of the container.

It is also an object to provide certain details and specific features of construction tending to increase the general efficiency and desirability of a paste container of this particular character.

To the foregoing and other useful ends, the invention consists in matters hereinafter set forth and claimed and shown in the accompanying drawing in which- Fig. 1 is a perspective of a paste container embodying the principles of the invention.

Fig. 2 is a vertical section of the said container.

Fig. 3 is a perspective of the sack or bag filled with paste.

different form of the invention.

Fig. 8 is a fragmentary detail sectional view of the bottom portion of the container, showing a different form 'of the invention.

Fig. 9 is a view similar to Fig. 8, showing a different form of the invention.

Fig. 10 is an enlarged detail fragmentary sectional view of the upper portion of the container, showing a different form of the invention.

As thus illustrated, the invention comprises a container in the form of a metal can I having its bottom or under side provided with an opening 2 and having its top provided with a shoulder P cap 3 forced into telescoping contact with the upper portion of the container. A sack or bag 4 is filled with the desired paste, and folded over or closed at its upper end 5, and glue 6 is then applied to the said top of the bag, to fasten the upper end of the latter to the under side or inside surface of the shoulder vcapil previously mentioned. A cap 1, of any suitable character, is forced or screwed or otherwise applied to the neck 8 of the shoulder cap 3, forming the discharge outlet for the container.

Obviously, a finger pressed against the lower end of the sack or bag will cause the paste to be expelled through the said discharge outlet, thus obviating the necessity of using an expeller in the can to communicate the pressure to the said sack or bag.

As shown in Fig. '7, the upper portion 9 of the sack or bag is folded over and held between the outer surface of the container and the inner surface of the shoulder, cap 3 previously mentioned.

In Fig. 8 the construction is similar to that shown in Fig. 2, except'that a fiber disk It), or disk of any suitable material, is shown glued or otherwise fastened to the lower end of the sack or bag, to communicate the pressure from the finger to the paste.

In Fig. 9 the construction is similar to that shown in Fig. 2, except that in this case a disk I l is enclosed within the sack or bag, at the bottom thereof, to communicate the pressure to the paste.

In Fig. 10 the construction is similar to that previously described, except that in this case the upper endv of the sack or bag 4 is provided with a plastic neck I2, which is rigid with the shoulder cap 3, and a closure or cap I3 is suitably applied to said neck.

.There are different ways in which the parts can be assembled. For example, the sack or bag the latter is fixed on the container body.

obviously, the sack or bag can be filled either can be filled and then forced into position with its glued upper end against the under side of the shoulder cap. On the other hand, the sack before or after it is incorporated in the container, in various ways, depending upon what methods or what kind of machines are used for doing the work.

It will be understood, of course, that the sack or bag 4 can be made of any suitable or desired material that will not injure the paste, such as Cellophane or other thin flexible material, but it should be tough enough to prevent. breakage and,

consequent leakage of the paste from the bottom of ,the container. With the top of the bag just loosely folded over, as shown in Fig. 3, pressure on the lower end of the sack will cause the paste to in effect burst through between the folded over edges he upper portion of the sack, when it is desired to expel the paste throughthe discharge outlet. But if the upper end of the sack or bag is provided-with a rigid neck, say of some plastic material, as shownin Fig. 10, then there will be no disruption or distortion of the upper portion of the bag when the paste is discharged.

In Figs. 8 and '9 of the drawing it may not be necessary to fasten the upper end of the bag to the container, inasmuch as in these two forms of the invention the bead H around the bottom opening of the container is adapted to co-operate can be employed to-prevent an accident of this kind. V

'Ifthe disk 9 is used, as shown in Fig. 8 of the greater length at its lower end, to provide any desired clearance between the bottom of the bag or sack and any surface or objectupon which the I container might be placedupright.

The sack or bag not only provides a means for inserting and containing the paste in the container, but also prevents the paste from smearing any inner surface with which an inserted finger. or fingers might come in contact. In addition, it will be seen that the sack or bag is of such shape and size that it fits or conforms to the side and top walls-of the container, whereby practically the entire capacity of the container is utilized when it is filled. i

It will be understood, of course, that the invention is not limited to the use of any particular materials, for the body of the container, inasmuch as there are obviously many materials other than metal which can be used for this purpose, in order to insure enough stifiness or rigidity to maintain the desired fixed form and shape of the container.- It will be seen that the bottom of the bag, in each form of the invention, is closely adjacent to the finger opening in the bottom of the rigid container body, so that in each form of the invention the finger pressure is practically directly against the bottom of the bag, but the latter is held in one way or another against falling out. Therefore, when the paste is exhaustedthe whole thing is useless for its original purpose and will be thrown away.

Obviously, the sack or bag 4 may be of any suitable or desired material that is impervious to any attack ofanything in'the paste, so that the can I may be of any cheap metal, such as ordinary tin. Thus a protecting cover means is permanently fastened to the container body and covers the entirejnner surface thereof, and also covers the inner surface of, theexpeller llL'for example, so that when the container-is full the paste is nowhere in contact with the material from which the containerbody is made, or-with drawing, this disk can be glued to the bottom of the sack or bag, or it can be left loose and separate, and when thus separate and loose the disk would be in the nature of an expeller-inter- 1 mediate the, bag and the finger or fingers of the hand. While a bead M is shown to prevent the disk from dropping out, it is obvious that other formations of the metal container can be used for that purpose. Thus with the sack or bag fastenedin place at its .upper end, adjacent the discharge outlet, it is obvious that an expeller is not necessary to keep the sack or bag from dropping out of the container. A disk of thin paper can be pasted over the opening 2, when the article is sold, which can be broken to exert pressure against the sack or bag. But with the latter fastened securely in place atits upper end, at the discharge outlet, the lower end of the sack or bag cannot sag seriously, and even if it should sag somewhat below the lower end of the container body, no harm would result, as the sack or bag can be made of very tough material which could not be punctured or injured by contact with a shelf or table or by anything upon which the container might be placed upright. While in Figs. 2, 8, and 9, the lower end of the can does by the paste. For that broad purpose, therefore the protective lining can be of any suitable or".

known or approved substance.

What I claim as my invention is:

l. A containerfor paste, comprising a body fo'f fixed form and shape, having means providing a dischargeoutlet for the paste, and having one wall thereof provided with an opening, and a bag containing the paste in said body, so that a finger or other means can be inserted through said opening into'direct engagement with the bag, thereby obviating the necessity of using an expeller in the container, said container having a shoulder cap providing said discharge outlet, with adjacent portions of the bag glued to the inner surface of said shoulder cap, thus fastening the bag permanently within the container.

2. A container for paste, comprising a body of fixed. form and shape, havingmeans providing a discharge outlet for the paste, and having one wall thereof provided with an opening, and a bag containing the paste in said body, so that a finger or other means can be inserted through said opening into direct engagement with the bag, there- 7 by obviating the necessity ofv using an expeller in the container, said bag having a relatively stiff disk secured to its bottom end, inside thereof.

3. A container for paste or the like, comprising an upright hollow body of fixed form and shape, having the entire bottom thereof left open, a bag of thin flexible material containing the paste and conforming entirely to the inner surface of the side walls .of said body, when the container is filled with paste, whereby the capacity of the bag is practically the same as the capacity of said body, and so that only the bottom of the bag is subject to pressure through said open bottom. the construction thereby utilizing practically the entire interior capacity of said body for the paste, and means on the upper end of said body and thereby adjacent to the upper end of said bag or sack for discharging the paste when pressure is exerted against the lower end of the bag, said bag having a disk of relatively stiff material at the bottom thereof, to receive said pressure.

4. A paste container comprising an outside container of fixed form and shape, wide open at the bottom, an inside container of flexible material for holding the paste. means to fasten the upper end of the inside container to the upper end of the outside container, and means at the top of the container for discharging the pastewhen said inside container is pressed through said ope'l bottom, said outside container having its top formed by a. shoulder cap, and said fastening means comprising an adhesive between the under side of the shoulder cap and the top wall of said inside container.

5. A rigid container body of fixed form and shape, open at its bottom to provide a finger opening, a discharge nozzle at the top, and a flexible bag containing paste and conforming to the interior of said body, so that practically the entire P capacity of said body is utilized, with the bottom of said bag closely adjacent to said opening, in position to'be gradually pushed toward the top, but the bag being held against falling out, so that when .the paste is exhausted the whole thing is then useless for its original purpose and will be thrown away, the bottom of said bag having a flat plate to receive finger pressure.
